Filter by:Cirrhosis is a diffuse lesion characterized by architectural distortion of the liver because of collagen deposition and development of nodules of regenerating hepatocytes. It is an irreversible change that results from diseases characterized by chronic liver injury (Fujimoto, 2000). Cirrhosis alters the pattern of blood flow through the liver and results in impaired perfusion of hepatic lobules with intrahepatic and extrahepatic shunting of blood. This deprives hepatocytes of uniform perfusion by arterial and portal venous blood resulting in both portal hypertension and other consequences of cirrhosis including impaired protein synthesis and altered drug metabolism. The histologic diagnosis of cirrhosis requires the presence of regenerative nodules or pseudolobules completely encircled by fibrosis such as congenital hepatic fibrosis can result in portal hypertension in the absence of cirrhosis (Anthony et al., 1977). The events leading to the development of cirrhosis are generally those of chronic injury with hepatocyte destruction. Acute severe liver injury as in fulminant viral hepatitis does not result in cirrhosis and the liver generally returns to normal after recovery. Cirrhosis can be classified by macroscopic appearance, by cause, and by histologic appearance and location of liver damage. Micronodular cirrhosis is composed of uniform nodules less than 3 mm in diameter, whereas macronodular cirrhosis has varying size nodules greater than 3 mm diameter. Mixed nodular cirrhosis has nodules of both sizes. Some liver diseases such as alcoholic liver disease may present as micronodular cirrhosis and develop larger nodules with subsequent regeneration of hepatocytes. For this reason, many prefer etiologic classification (e.g., alcoholic cirrhosis). The designation of cirrhosis as post necrotic, biliary and portal are still commonly used and imply predominant histologic location of fibrosis. Cirrhosis is an irreversible disease, and attempts should be made to stabilize the patient and to control the cause. Factors that indicate a poor outcome include an elevated prothrombin time that does not correct itself with parenteral vitamin K, upper gastrointestinal bleeding caused by varices, ascites refractory to therapy, increased age of the patient, sever malnutrition, spontaneous bacterial peritonitis, a pronounced increase of serum bilirubin in the absence of haemolysis, and heptocellular carcinoma (Yeh et al., 2003). In general, all causes of upper GI bleeding are associated with an increased mortality in patients with cirrhosis. For those with alcoholic cirrhosis who lack portal hypertension, survival is similar to an age-matched cohort if alcohol intake is stopped (Nakamura et al., 1991). If ethanol consumption continues, mortality is higher. Cirrhosis can be present without clinically significant complications and be identified only at autopsy or during evaluation of abnormal liver tests (Mendez et al., 2003). However, for many patients the disease is slowly progressive resulting in one or more complications. The clinical manifestations of cirrhosis are a result of altered hepatic blood flow through the liver with intrahepatic shunting causing impaired perfusion of hepatocytes or portal hypertension with shunting of blood around the liver though portosystemic communications. The major complications of portal hypertension include oesophageal or gastric varices, ascites, portosystemic encephalopathy, and hepatorenal-syndrome (Menon & Kamath, 2000). With impairment of hepatocyte perfusion or reduction of hepatocyte number, altered synthetic function can result in hypoalbuminemia, hypoprothrombinemia, and changes in drug metabolism. Vitalliver is a Chinese medicine which is administered in the form of a suppository, which is uncommon for most Chinese medicines. Medications released from the suppositories are absorbed directly from the circulation around the rectum and then reach the liver via the portal vein. Basic pharmacological studies have shown that Vitalliver has good immunomodulating functions, increases the activities of T-cells, B-cells and NK cells, therefore this formulation may have special values in treating liver diseases.
The primary hypothesis is that INT-747 will cause a reduction in alkaline phosphatase levels in Primary Biliary Cirrhosis patients, over a 12 week treatment period, as compared to placebo.
The primary purpose of the trial is adopted Fuzheng Huayu tablets against posthepatitic cirrhosis, and to build a standard evaluation system for efficacy of traditional Chinese medicine (TCM). The second purpose is according to the international clinical guideline and the specialty of TCM to build a standard clinical trial regulation for traditional Chinese medicine.
To Elucidate and Confirm the Theory of XuSunShengJi in the Traditional Chinese Medicine Etiological Pathogenesis of Liver Cirrhosis.
Intervention to achieve alcohol abstinence represents the most effective treatment for alcoholic patients with liver cirrhosis. However no trials have evaluated the efficacy of anti-craving drugs in these patients because of the concern that these medications might worsen liver disease. Baclofen is effective to reduce alcohol craving improving abstinence in alcohol-dependent patients. It is mainly eliminated by kidney. No hepatic side-effects have been reported in treated patients. The present study investigates the efficacy and safety of baclofen in achieving and maintaining abstinence in alcoholic cirrhotic patients.
Physical training improves quality of life (QOL) in non-hepatic diseases. It is possible that the same effect happens in patients with cirrhosis and portal hypertension. Hepatic encephalopathy may also benefit from physical activity by increasing ammonia metabolism. The intention of this study is to assess if patients can improve their QOL and hepatic encephalopathy during a physical training program, and to address its safety.
Cirrhosis is frequently complicated by derangement of body fluid homeostasis resulting in accumulation of large amounts of extracellular fluid in the peritoneal cavity (ascites) and interstitial tissue (edema). Studies showed that patients with cirrhosis and ascites have marked circulatory dysfunction. Albumin infusions have been used for many years in the management of patients with cirrhosis and ascites in an attempt to reduce the formation of ascites and/or improve circulatory and renal function. While some of these indications for albumin infusions are supported by the results of randomised studies, others are based on clinical experience and have not been proved in prospective investigations. Therefore, the use of albumin infusions in patients with cirrhosis is controversial. Recently, this debate has been fostered by the high cost and limited availability of albumin and the results of a meta-analysis showing that albumin administration may increase mortality in critically ill patients. In cirrhotics, there is a significant improvement in the low effective arterial blood volume, which may be important in the prevention of circulatory dysfunction and in preventing renal impairment. However, in an already fluid overload state such as that of cirrhosis, albumin infusion predisposes the individual to develop pulmonary edema. There is no study demonstrating acute effect of albumin infusion on hemodynamic parameters, in cirrhotic patients. Neither is there is data concerning comparison between albumin and normal saline. It is postulated that it may increase portal pressure thereby increasing the risk of variceal bleed. This study hypothesizes that albumin infusion might lead to alteration in portal and pulmonary hemodynamics in decompensated cirrhotic patients. Included patients of cirrhosis with ascites (based on inclusion and exclusion criteria) will undergo baseline investigations (systemic hemodynamics, pulmonary hemodynamics, portal hemodynamics). They will be randomized into two groups, each of 8. One group will receive infusion of 100 ml 20% albumin over 3 hours, and the other will receive infusion of 100 ml normal saline over 3 hours. Repeat hemodynamic studies will be performed after the infusion finishes. All results will be expressed as mean ± SD or frequency (%). Comparisons will be performed by the Student's t test or with the Wilcoxon's test
The purpose of the study is to evaluate whether Viusid, a nutritional supplement, reduce the mortality and the complications (ascites, spontaneous bacterial peritonitis, hepatorenal syndrome, hepatic encephalopathy, gastrointestinal bleeding, sepsis and hepatocellular carcinoma) of patients with cirrhosis of the liver secondary to HCV infection in comparison with placebo, during 96 weeks of treatment.
The primary objective is to determine the optimal dose or range of doses of SR121463B for the treatment of ascites and the correction of hyponatraemia when used concomitantly with a standard dose regimen of spironolactone. The secondary objective is to determine the tolerability of different fixed doses of SR121463B over a 14 day treatment period in cirrhotic ascites. This Hypo~CAT study is followed by a single-blind, placebo-controlled, one-year long-term safety extension (Expo~CAT). The first extension is followed by another long-term study (PASCCAL-1).
The primary objective is to determine the optimal dose or range of doses of SR121463B for the treatment of ascites when used concomitantly with a standard dose regimen of spironolactone and furosemide. The secondary objective is to determine the tolerability of different fixed doses of SR121463B over a 14 day treatment period in cirrhotic ascites.
